In various industrial applications, turbulence can be affected by density variations resulting
from different origins acting simultaneously. This monograph is intended as a first attempt to …

In this study we characterize the turbulence, by means of energy spectra, characteristic
turbulence length scales, energy dissipation, kinetic energy decay rate etc., behind a set of …

This paper presents a class of turbulence models written in terms of fractional partial
differential equations (FPDEs) with stochastic loads. Every solution of these FPDE models is …

Reynolds stress budgets for both Couette and boundary layer flows are evaluated and
presented. Data are taken from direct numerical simulations of rotating and non-rotating …

This experimental study deals with the effect of externally generated turbulence on the
oscillatory boundary layer to simulate the turbulence in the wave boundary layer (WBL) …

The capability of rapid distortion theory to predict the long-time evolution of shearless
turbulence close to an impermeable surface has been seriously questioned in recent years …

The interaction between oscillating-grid turbulence and a solid, impermeable boundary
(positioned below, and aligned parallel to, the grid) is studied experimentally. Instantaneous …

We report an experimental study of a new type of turbulent flow that is driven purely by
buoyancy. The flow is due to an unstable density difference, created using brine and water …

We report on direct numerical simulations to examine the spectral behaviour of turbulence
close to and at a flat, stress-free surface. We find, consistent with field measurements near …

Over the years, many facilities have been developed to study turbulent flow in the laboratory.
Homogeneous isotropic turbulence (HIT) with zero mean flow provides a unique …
